As a woman and a mother who is deeply concerned about climate change, a decision by the California Public Utilities Commission (CPUC) a few weeks ago enabled me to take a break from my feelings of dread. In fact, I all out rejoiced.

On June 21, 2018, the five-member CPUC swiftly and unanimously decided to reject San Diego Gas & Electric (SDG&E) and Southern California Gas’ (SoCalGas) bid to install a 47-mile-long, 36-inch diameter gas pipeline in San Diego County. The pipeline had been contested by Santee residents, and environmental groups, such as Save Mission Trails and Sierra Club, since one potential route would have taken it through Mission Trails Regional Park.

The line would have been named Pipeline 3602.

After the vote, I felt confident that California state agencies are truly committed to environmental protection.

Matthew Vespa, staff attorney for EarthJustice, said “It’s actually thanks to everything California has been doing that we don’t need this pipeline. Midway through this case, the legislature passed SB 350 and SB 32. That helped us a lot; it helped us to tell the story that this is where we are going, and fossil fuels don’t have a place in that world.”

Senate Bill 350, the Clean Energy and Pollution Reduction Act, requires a 50 percent renewable portfolio standard (RPS) by the year 2030. That is, this standard requires that half of the utilities’ energy sales must be from renewable resources, such as solar or wind energy.

To meet these goals, a whole suite of measures must happen. Presently, we are seeing massive electric vehicle charging investments. The California Energy Commission recently passed regulations requiring solar panels on nearly all new houses, with additional incentives for electric space and water heating. Locally, six cities that make up 50 percent of San Diego County’s population have committed to obtaining 100 percent of their electricity from clean energy sources by 2035.

“All of these things add up to reduce gas demand, thus making the need for the pipeline obsolete,” Vespa continued.

With the CPUC vote, California announced that investing in new fossil fuel infrastructure makes no sense.

The CPUC determined that SDG&E and SoCalGas had “not shown why it is necessary to build a very costly pipeline to substantially increase gas pipeline capacity in an era of declining demand and at a time when the state of California is moving away from fossil fuels.”

From the time the utilities’ proposal to build a new pipeline first crossed his desk, Vespa started to argue that the line would become a stranded asset.

“The pipeline already would not have been necessary on its first day of operation, which would have been in 2023. Its usefulness would have decreased every year after that,” he said. “By 2050, we should have moved past relying on fossil fuels at all. Yet, San Diegans would have been paying over $2 billion up until 2063 because of the way the revenue requirement works.”

With the CPUC vote on Pipeline 3602, California asserted that economic prosperity and environmental sustainability are not mutually exclusive.

“We can get to these climate goals and a basically carbon-free energy system at the same cost as a business-as-usual scenario, provided we don’t invest in fossil fuel infrastructure, provided we pivot to clean energy at every opportunity,” Vespa said.

California is well on its way to reaching the 50 percent RPS goal. In 2017, the California Energy Commission reported that about 30 percent of retail electricity sales in California were from renewable sources, mostly wind and electric, but also geothermal, biomass, and small hydroelectric.

By rejecting the pipeline, California showed it takes the climate change crisis seriously. And crisis it is. According to the majority of climate scientists, the earth’s average surface temperature has increased by more than 1.4 degrees Fahrenheit over the past 100 years. This temperature rise coincides with the time period in which humans engaged in large-scale endeavors to extract and burn buried hydrocarbon resources (fossil fuels), including coal, oil and natural gas.

NASA reported that 2016 was the warmest year on record globally. The U.S. Forest Service reported that, in that year alone, 62 million California trees died. Since 2010, 102 million died in the state’s drought-stricken forests. Across the world, heat waves are longer, glaciers and ice caps are melting, and animal species are facing extinction.

Bill McKibben, who founded the environmental group 350.org, warns if we don’t act fast, eventually we will have a climate that can no longer sustain civilization as we know it.

On June 21, 2018, the day the CPUC rejected the utilities’ proposed natural gas pipeline, California showed it’s not going to be stuck in the past; it’s moving forward with resolve and innovation.

California, as a trailblazer and the sixth largest economy in the world, is going to continue to prove that environmental sustainability and economic prosperity can go hand in hand. My hope is that the rest of the nation will follow suit, quickly.
